To allabb'om' it may concern:

State of New York, have invented a new and useful Air-Cooling System forInternaling'is a specification: 7 i My invention has for its 'objectapartlcularly simpleand'eflici'ent air cooling system for internalcombustion engines ofmotor Combustion Engines, of. whichthe followvehicles; and it consists in thecombinations Q and constructionshereinafter set forth and claimed.-

In describing this invention reference is had to the accompanying drawng in wlnch parts in all the viewsij; v a Figure 1 1s a longitudlnalsectlonal vlew,

like characters desig'nate corresponding .partly in elevation of aportion of a vehicle embodying my invention,jp'arts of the engine beingomitted. Fig. 2.is a plan of parts seen in Fig. the hood being removed.Fig.

and flanges set therein,

The invention comprises, generally, a,

g air cooled cylinders,

3 is a sectional view on line AA 2, the engine and other parts beingomitted. Fig. 4 is a detail View of one of the cylinders casing, for anengine having a plurality of a transversely disposed partitiondividingthe easing into two compartments, the upper of said compartments havingan inlet -opening, ,and the lower of the compartments an exit opening,'saidpartition having means individual to the cy1inders of theingineforatfording communication between the two compartments and for bringingair in its passage from one compartment to the other into intimatecontact with the cylinders throughout a'major part of the'lengththereof, andja peripherally discharging suction fan, located adj acentthe said exit opening, and of the type which will move a la'rge' volume,or body, of air comparatively :slowly.

In the illustrated exemplification of my invention, 1 indicatesthe .sidesills of the frame, or chassis,. of a motor vehicle, 2 the dash-boardthereof and 3 the engine, consisting of a base frame housing thecrankshaft, and a plurality of upright cylinders arranged. in tandemformation and equipped with suitable heat conducting ribs, or fins,which are preferably formed separate from the cylindersand setintogrooves therein,

The casing preferably houses the entire engme and comprlses a lowersection, or boot 6, an-upper section, or hood 21, and a transverse lyextending'partition dividing the easmg into upper and lowercompartments. The lower section,-or boot 6, is secured at its side upperedges a front plate, or wall 8, a substantially semicylindrical bodyportion flaring downwardly and rearwardlyfrom the front plate, and arear Wall 15 having an opening 16 therein. "The upper section, or hood,of the comprises a substantially semi-cylindrical plate, abutting at itsrear edge against the front face of the dash-board 2 and having sideflanges 23adapted to rest plate having an opening 22 therein, andbrackets 24, carried by the front plate and engaging pins 25 extendinginwardly from the sills 1, for prowhich the to the sills 1, and includesPatented Feb. 8,1916.

The partition includes a substantially horizontally' disposed top plate7 extending lengthwise of the casing in a plane intersecting thecylinders betweenthe ends thereof, and-provided at its 'rear end with anup- .wardly extending flange 19 secured to the down front face of thedashboard 2, and a \vardly extending wall M having therein an openingcooperating with the opening 16 for providing the airexit from thecasing. The partition further includes a front plate 12 havinga portion'of its upper edge secured to the plate 7 and its the upper edge of thefront Wall 8 of the boot, and side plates .9, secured at their uploweredge secured to per side edges to the side edges of the plate 7 andprovided at their lower side edges upon the sills'l, 'wit'n flanges 13overlapping portions of the upper edge of the plate 12.'

The major portion of each plate.9 is preferably displaceable soas toafford access to the lower compartmentof'the casing and for this purposethe upper edge of each of said -nia'jor portions is preferably hinged tothe edge of the plate 7in any suitable manner.
